Latest Patents

Varma holds a patent for a groundbreaking invention titled "Strong, flexible, and thrombus-free woven nanotextile based vascular grafts, and method of production thereof." This patent describes an apparatus for the fabrication of a woven tubular nanotextile specifically designed for vascular graft applications. The innovative conduit ranges from 0.1 to 50 mm in diameter and features a multitude of hierarchically arranged nanofibers. These nanofibers are constructed from low strength bundled nanoyarns, consisting of thousands of nanofibers that significantly improve mechanical strength. The weaving apparatus employed interweaves warp and weft yarns in both longitudinal and transverse directions, which results in a flexible and robust woven product.

The resulting woven nanotextile provides enhanced physical and biological properties compared to non-woven nanofibrous forms and traditional medical textiles. Notably, it exhibits superhydrophilic behavior in an otherwise hydrophobic material, and when implanted as a vascular graft, it demonstrates remarkable robustness, being both suturable and kink-proof. Furthermore, it is labeled as non-thrombogenic and achieves complete endothelialization within the graft's luminal area.
